Abstract

A readily soluble 2',3'-dideoxyinosine composition is prepared by combining 80 to 1 parts by weight of a basic amino acid and 20 to 99 parts by weight of 2',3'-dideoxyinosine. The greater solution velocity of this composition improves solubility for therapeutic uses.

Claims

exact text as granted — not AI-modified
What is claimed as new and desired to be secured by Letters Patent of the United States is: 
     
       1. A powdered 2',3'-dideoxyinosine composition consisting essentially of 75-9 wt % arginine and 25-91 wt % 2',3'-dideoxyinosine, said composition having a solution velocity of 70-140 seconds at 20° C. per 1 gram of said composition in 100 ml water. 
     
     
       2. The composition of claim 1, wherein said composition consists essentially of 75-41 wt % arginine and 25-59 wt % 2',3'-dideoxyinosine. 
     
     
       3. The composition of claim 1, wherein said composition consists of 75-9 wt % arginine and 25-91 wt % dideoxyinosine.
